To all whom it may concern.

Be it known that I, Citizen of the United Philadelphia,

JACOB KAUFMANN, a States, residing at in the county of Philadelphia certain new and 'useful Improvements in HeddlesFrames, of whichthe following is a specification.

y invention relates to heddle frames for looms, and it has particular relation to means for supporting the heddle bars interpermit the bars to be easily mounted in and dismounted from the frame when desired.

Heretofore various devices have been employed to support the heddle bars intermediate their ends to ment or distortion while in use, these devices commonly consisting of hooks of various shapes which were secured to the frame and were usually open atthe end toward the heddle frame rail to permit the insertion of the heddle bar. On account of one end of these hooks being open, the heddle bar was permitted considerable movement during the reciprocation of the heddle frame in the loom, which movement would be suddenly arrested on the reversal of the motion of the heddle frame by the bar striking against the hooks to quickly wear through and permitting the bars to become disp aced'. The destruction of a large part of the structure by fouling of adjoining harness was frequently :0 caused in this manner.

My present invention contemplates a form of sup orting means which, permitting the ready insertion of the heddle bar, yet will maintain the same against undue movement 5 and thereby overcome the objections above the mam features of my present invention Pennsylvania, have inventedprevent their displacethe hook,- thereby causing the elevation of a heddle I shown mounted therein; Fig. 2 is an enlarged side elevation of vice detached, but with a portion of the heddle barv shown in operative relation thereto; Fig. 3 is a similar view, but taken transverselv to Fig. 2; Fig. 4 is a horizontal seetion, still further enlarged, of the supporting device, the section being taken 'on the line 44 of Fig. 3; Fig. 5 is a fragmentary perspective view of the supporting member, a portion of the heddle frame in which it is mounted, and a portion of the heddle bar in its normal mounted position; and Fig. 6 is a view similar to Fig. 5, but with the parts in the positions assumed during the insertion of the heddle bar in the supporting member. 1 i

Referring to the drawings, the heddle frame there shown consists of the top and bottom rails 7, usually made of wood, and connected at their ends by means of the end straps 8. Extending from end to end of the heddle frame, and arranged near the top and bottom rails in the usual manner, are the heddle bars 9, upon which the heddles 10 are mounted.

The supporting device forming the novel portion of my present invention comprises a screw-threaded shank 11 which is adapted to be screwed into thetop and bottom rails 7 at the desired locations. The rails"? are usually made of wood, although in the event the supporting deof their being made of metal, it will be readily understood that the shank ll may be modified accordingly, the essential being that this shank may be capable of forced rotation' with respect to the rails 7, but against the frictional resistance by which they are held in the desired positions. Secured to the threaded shank 11 in any suitable manner are two parallel plates 12 which, as shown, may be secured by means of a rivet 13 to the screw-threaded shank 11, and are prevented .from rotation about saidrivet by making their ends bifurcated and having the bifurcated portion bent over as at 14 to engage the shank 11, as clearly shown in Figs. 2, 5 and 6 of the drawings. Ifdesired the plates .12 may be welded to or formed integral with the shank 11. The plates 12 are separated from each other a distance at least equal to the thickness of the heddle bars 9, and each of said plates is provided with a recess 15 which extends "to the edge of the other to the edge of one plate 12 at one side and late 12 on the opposite side as shown in g the drawings. The recess 15. is of a width corresponding to the width of the heddle bar 9 which isjsupported therein in the assembled condition of the structure as shown in 1 to 5 of the drawings.

'Ilie heddle bar 9 is inserted in the supporting memberby first turning said memher until the plates 12 lie parallel to the sidewise movement.

longitudinal extension of -the frame rails 7 as shown in Fi 6 of the drawings, whereuponthe heddle ar-9 may be inserted betweensaid plates until it-occu ies a osition opposite the recesses 15, a r w ich the sup porting member is turned 90, against the frictional resistance offered by the rail 7 in which it is mounted, until it occupies the osition shown in Fig. 5, whereupon the so id -portion ofeaclilfplate 12 opposite its recess the bar 9 against undue It should be understood that the heddle supporting bars 9 are will serve toco ne usually rectangular in cross ,SQCtIOII and are limited in their transverse dimensions on account of the relatively small ermissible size of the mortised ends of t e heddles which are mounted thereon. On account of this limited dimension, where these bars are of great length, they are likely to be distorted sidewise du rin the reciprocation of the heddleframes in t e loom.
